Popis: International audience; Optical, structural and electrical properties of new cobalt phthalocyanine derivatives (Co(II)Pc-AP) thin films have been investigated. The Raman spectroscopy study shows the different vibrations bands corresponding to the metallophthalocyanine. The cobalt-phthalocyanine derivative films exhibit absorption spectra with a resolved electronic structure in the UV-vis range and the energy gap was determined by the Tauc method. Electrical properties of the ITO/Co(II)Pc-AP/Al structure have been investigated by I-V characteristics and impedance spectroscopy measurements. The conduction is governed by space-charge-limited current (SCLC) mechanism. The impedance spectroscopy study showed a hopping transport process, which is a typical behavior of disordered materials. The electrical characteristics of the devices were modeled by a single parallel resistor and capacitor network in series with a resistance.
